This invention relates to improvements in edge rolls for use inupholstering parts such as spring assemblies.

The main objects of this invention are:

First, to provide an edge roll for upholstering spring assemblies andthe like which may be quickly and easily applied and is very securelymounted with the outer edge of the roll substantially projecting beyondthe border of the spring assembly or Vin` proper..relation to theparttobe upholstered. y y

Second, to provide an` edge roll having these advantages which may besecurely applied or attached bymeans of clips, commonly referred to as-hog rings in the upholstering industry as distinguished from sewing. YI

.Thirdf to .provide anedge roll. having these advantages in which thestrain upon the parts engaged by the clipswis distributed substantiallythroughout the length of the structure although the clips arelongitudinally spaced. Y

Other objects relating to details andeco-nomies of the invention willappear from the description to follow. The invention is dened` andpointed outinthe claims. A

Commonlythe spring assembly is covered-withv a fabric 6, such for example Vasburlap;` having a depending 'skirt A portion -"I,' the rupholsteringpadding and the coveringtherefor'not being i1'- lustrated. -1` j Ourimproved edgeiroll isdesignated lgenerally' byi-'thelnumerall 8 andlcomprises' an 'elongated 1o` claims. (ci. 155-184) 2 resilientcore .9.desirablyof crumpled or crushed paper. desirably twisted.4 `Arelativelyw softer padding I0` of. multiply cellulose tissue, some,-`timescommercially designated as cellulose wadding, is wrapped aroundthecore. The covering vII of fabric; desirably of burlap, completelyembraces the resilient body portion and is extended toprovideailapdesignated generally by the numerall I2. The padding ispreferably extended into the nap, the covering and the padding beinganchored and securedradjacent vthe inner edge of the core by means of arow of stitches I3.

The outer edges of the covering are wrapped around a beading orreinforcing cord I4 desirably of twisted paper and secured thereon by a.rod of stitches I5. VThis provides a reinforced flap `welladapted to besecured to the springs orother parts of the spring assembly by means ofthe clips I6 which are passed through the flap to embrace the stand I4and are clinched as indicated at I 'I in Fig. 2.

An attaching bead I8 is formed on the under side of the edge roll inspaced relationship to its outer edge. This comprises a fold I9 inthecovering I I which embraces a reinforcing or beading strand 20, alsodesirably formed `of twisted paper. The loop or fold in the fabric issecured around the reinforcing strand desirably by a row of stitches 2|at the inner side of the strand 20. 'Ihis bead may be attached tothebody frame by means of clips I 6. 'In the embodiment shown in Fig. 5 thebeading or reinforcing strand I4 is omitted. A single row of stitches I3is illustrated in the aps. This provides an economical structure butlacks the strength of the preferred structure.

If vdesired the flap 22 of this structure is adapted to receiveattaching clips or to be stitched or tacked to the` frame or part to beupholstered. The beading I8 of this structure provides effective meansfor attaching with the outer edge of theredge roll projecting thedesired amount.

Inthe structure illustrated, the edge roll is of inwardly taperedsection. The edge roll of our invention is adapted for a wide range ofuses or applications and may be effectively applied by others thanskilled upholsterers.

We have illustrated and described our invention in av highly .practicalembodiment thereof.
